Cheers, great post.

Adding the ones involving a pro club or clubs playing in a top flight to the OP.

I must admit the only player I've heard of out of those is Alec Vinci and that's because he made his one and only CCM appearance against us in the Cup.

Both

Hopefully Alou can fill gap left by Cummings - and even dislodge JMac for Roos selection

A few lesser known Aussies that I couldn't see listed:
BONNICI, Duane (10 Oct 1995) - transferred to Marsaxlokk, Malta (1)
CAMPANA, Enzo (7 Aug 2003) - transferred to FK Jedinstvo, Montenegro (1)
FAUX, Joey (8 Jul 1999) - transferred to Connah Quay Nomads FC, Wales (1)
PULJIC, Ivan (3 Jan 1998) - transferred to FSC Eschborn, Germany (5)
SMITH, Bradie (2 Nov 1988) - transferred to Resources Capital, HK (1)
SWANSON MANUEL, Santino (29 Dec 2000) - transferred to UD Fuente de Cantos, Spain (5)
VELARDI, Domenico (19 Jan 2003) - transferred to FK Jedinstvo, Montenegro (1)
VINCI, Alec (2 Oct 1999) - transferred to FC Wegberg-Beeck, Germany (5)

I wonder if Alou is coming back on loan or permanent transfer.

If permanent transfer and he signs on for a few years, I can see us generating another transfer fee for the same player. 

Is it me or heaps of players getting decent moves? 

Alou Kuol back to Mariners. Good I say. Top first season in the German fourth tier only for odd circumstances in the second year.

Don't think it's fair to say he's come back with his tail between his legs. Plenty more have falsely persevered and jeopardised their career. Good to get out early.

Especially in a league where the salary cap is around 2.4 million I believe. Throw in Kuol and some other mid season moves the mariners had and they’d be around the same amount as city. Fantastic business for both clubs

Would it be safe to say Mariners would have received in the vicinity of $2 million for their transfers this window (Triantis, Silvera, Cummings), whilst Melbourne City would be in the region of $4 Million (Tilio, Bos, Glover)??

Thats great business and a really good sign for the league. 

Here's hoping. A lot of young players to bigger named clubs this window. Wonder what Tyrese Francois will end up doing?

Reports are he has been signed to the U21s initially.

Fulham sign Donnell from Perth Glory

Interesting but we've seen it all unravel before. Hopefully there's a high prospect of games for the reserves or academy. 

Does he request an immediate League 2 loan? A full year of first team football is needed. At the same time these EFL clubs are all becoming pretty ambitious and aren't just handing out games to loan players these days. AMB went below the EFL for a year and that seemingly paid off. Despite the A League being the higher level, the amount of available football in England is almost double. 

Perth Glory also just confirmed that Chris Donnell has been transferred to Fulham

WU have signed Kane Vidmar, the son of Tony on a scholarship deal from our youth team

Antonis has signed for City, presumably as a squad player

I was just reading about that.

Dave Penha looks like going WU

Tom Glover is linked with Middlesbrough 

Sydney have sold Diego Caballo to AaB Aalborg

This has just been confirmed now.

From Sydney FC to VfB Stuttgart ✈️🇩🇪

Congratulations to Sydney FC's Rawley St. John on securing a European move!

He posted on insta that he was in contract negotiations and then the club chose not to renew his deal.

I don't think Acton is any worse than what Holmes is tbh.

There's clearly more to this story which will hopefully come out. Is he waiting to try and get an overseas gig? If Roar had the opportunity but didn't re-sign him and instead have gone for Acton, a clearly inferior keeper, then something is up, unless he was looking for too much money?

Jamie Young to Melbourne City

Jordan Holmes has joined NPL Queensland side Rochedale Rovers

Donachie to Western United

Blackwood and Kasumovic released by Adelaide United.

Sydney youth keeper Max Vartuli has signed a 2-year deal with AaB Aalborg after a successful trial.

Edit: it was a two-year loan
